How to address daylight saving time by using the Exchange Calendar Update Tool

Cumulative time zone updates contain only data that has changed for a specific region or that was added to maintain parity with other operating system versions. Therefore, if a time zone key is deleted, some original values may not be restored after you apply the cumulative zone update.We do not recommend that you delete any registry keys that are related to time zones. On a computer that has incomplete time zone keys, first restore the time zone keys from a known good backup. Then, apply the update.

The update that this article describes changes the time zone data to accommodate daylight saving time (DST) changes in several countries. This update also includes other DST-related changes, time zone-related changes, and settings-related changes. Some of these changes have occurred since the products that are listed in the "Applies to" section were originally released.

The update that this article describes is a cumulative update rollup that includes all the changes that were previously released in Microsoft Knowledge Base (KB) articles 928388, 929120, 933360, 942763, 951072, 955839, 970653, 976098, 981793 and 2158563.

Updates from the previous cumulative Windows time zone update

The following changes were made since the previous Windows cumulative time zone update:

Magadan Standard Time:Creates Magadan Standard Time time zone with the display name of “(UTC+11:00) Magadan". This timezone will have DST support, with DST starting in March and ending in October. Removes "Magadan" from the display name of "(UTC+11:00) Magadan, Solomon Islands, New Caledonia" time zone, which does not have DST support.

Namibia Standard Time, displayname (UTC +1:00) Windhoek: Changes the time zone bias from UTC+2:00 to UTC+1:00. Changes the DST start and end dates, so DST starts in September and ends in April. These changes take effect starting in 2011.

EgyptStandard Time, displayname (UTC +2:00) Cairo : Sets 2011 DST start-date to occur in April and DST end-date to occur in September.

The English (United States) version of this software update installs files that have the attributes that are listed in the following tables. The dates and times for these files are listed in Coordinated Universal Time (UTC). The dates and times for these files on your local computer are displayed in your local time and with your current daylight saving time (DST) bias. Additionally, the dates and times may change when you perform certain operations on the files.

Windows 7 and Windows Server 2008 R2 file information
